LOSSES EROM CANALS BY SEEPAGE.

the strata exposed and with a decided dip offering an easy 
course for descending waters. 
The measurement showed a loss in 7 miles of over 15 
cu. ft. per second; or, starting from the river with 22.09 cu. 
ft. a little over 2 cubic feet being withdrawn by lateral 
ditches, there were left but 4.54 cu. ft. or there was a loss of 
a little over 15 cu. ft. per second. 
In the portion outside of the foothills occasional gains 
were found. In most cases the gain's were found to be asso- 
ciated with drainage areas of some extent. The soil is 
largely disintegrated granite, coarse and porous, and ab- 
sorbs rain very readily.
